Shell msdosfmt (format command) a NOOP with SD/MMC cards

4.9.1 shell command msdosfmt to an SD or MMC card results in no writes to the card so it is *not* reformatted.

This is caused by the read and write function for the driver interfacing being defined NULL. For standard disk file writing the correct functions are specified.

This can be manually fixed in 4.9.x by backporting the new HEAD version as described here to the 4.9.x code:

This new HEAD version also adds MMC support and High Capacity SD support.

If this works in 4.10 or 4.11, then I agree. If not, then I think
we need to change the milestone.

It is a wish for a back port. I wish they would upgrade. :)
